Unique Range Coil Coater Wet Film Thickness Gauge

Coil Coater Wet Film Thickness Gauge




The Coil Coater is a precision Wet Film Thickness Gauge with an available 2 - 6 mil Range Scale and 4 - 8 mil Range Scale, with smallest graduation 0.2 mils.



  • Direct Reading
  • High Precision
  • Circular Type
  • Standard Gauge For Testing Coil Coatings

These Coil coater gauges have an eccentric disk between two outer disks. This design is slightly different from the Gardco Model "C" wet film gauges that have the eccentric disk in front of the other two disks. (Reference leaflet "Model C Wet Film Thickness Gauge with Optional Handle".)

The gauge is in the form of a wheel, the perimeter having three equally spaced disks. The center disk is smaller and eccentric to the outer ones. When the gauge is rolled over a wet film, the center disk will pick up material immediately when contact is made. The reading is taken from the point at which this contact first appears. For this purpose, a calibrated scale is engraved on one side of the gauge so it is possible to read film thickness with an accuracy of 0.0002".

Instructions for Use

The gauge is placed on a freshly coated surface at the high range position (6 mils/or 8 mils) and rolled in one direction for one half a revolution. It is then lifted and placed on another area with its high range in contact with the surface. It is then rolled in the opposite direction for one-half a revolution.

Examination of the center disk will show positions at which pick-up has taken place and the scale will show wet film thickness at each point. For clear coatings, dust the center wheel with talc. Blow off talc. Talc will only adhere to wetted portion of disk. Read scale at end of wet point.

Gardco Coil Coater IC type Thickness gauge is rolled over the film and the wet film thickness is read directly from the gauge. Accuracy of 0.0002".

Optional Handle

Coil Coater Gauge Handle

A brand NEW ergonomic gauge handle is now available for use with the Coil Coater gauge. It offers a very comfortable precision grip handle that can be quickly and firmly attached to or removed from the gauge. It is useful as an aid in aligning the gauge on the test surface.

When the gauge is used on a moving surface, the handle aids the user to keep his hand at a distance from such surface. It also may prevent the possibliity of dropping the precision instrument onto a costly rotating roller.

The handle is about six inches long and is produced from solid bar stock aluminum. The handle axle is designed to accept all Gardco produced Model C gauges, IC gauges and Coil Coater gauge.

The gauge is held in place on the handle with one of the gauge grips so it is readily removable for cleaning or for reassembly for use of the gauge with grips only.
